I finished both the game and the DLC. It's a short little puzzle game with a quirky story that involves demon girls and a macho man. It's pretty fun and challenging, but not to the point where a guide is needed to figure out. The music is really good too. Considering it's a free game, it's really worth a try if you want a quick and memorable game. A huge fan base has spawned from the game and it's easy to see why.
